Abstract

The invention discloses a waste gas exhausting and recycling device for an anaesthesia machine for the anesthesia department. The waste gas exhausting and recycling device comprises an exhausting mechanism used for inhaling and a cleaning mechanism used for treating waste gas, wherein both the exhausting mechanism and the cleaning mechanism are mounted on a bottom plate; the exhausting mechanism communicates with the cleaning mechanism through a gas pump; under gas exhausting action of the gas pump, the exhausting mechanism rotates and cleans a contact surface; and the exhausting mechanism isarranged on a supporting barrel in a sliding mode. According to the waste gas exhausting and recycling device disclosed by the invention, in use, a gas exhausting cover is fitted to a waste gas outletof the anaesthesia machine, and then, the gas pump can be started for completely and intensively exhausting waste gas through a gas exhausting cover, and gas flow drives fan blades and bristles to continuously rotate to clean the position of a waste gas hole, so that a cleaning problem caused by impurity attaching can be avoided; harmful substances in the waste gas are removed after the waste gaspasses through an alkaline solution, alkaline steam in tail gas is cleaned by cleaning water and then is dried through active carbon particles for being discharged; and a gas exhaust pipeline can bedesigned to improve contact efficiency of the gas and the active carbon particles in the drying cavity to improve drying and drying treatment effect.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an anesthesia machine waste gas extraction and recovery device for an anesthesia department. Background technique

[0002] At present, the anesthesia machines commonly used in the anesthesia department of the hospital do not have an exhaust gas discharge system. The exhaust gas during anesthesia is usually discharged directly into the anesthesia operating room, which not only easily causes secondary inhalation of the patient, affects the inhalation dose of the anesthetic, but also easily Inhaled by medical staff in the operating room, affecting the normal work of medical staff, it is easy to cause dizziness, fatigue, lack of energy and other problems in a short period of time. Therefore, necessary devices are needed to discharge the anesthesia waste gas in time.

[0003] At present, for the discharge of anesthesia waste gas, the central waste gas pumping method is mostly...
